"A perfect recipe of humor, family connections, honoring the natural world, and a ghost with unfinished business." —Lynne Kelly, USA Today bestselling author of Song for a Whale Junior Library Guild Gold Standard Selection Ferris meets Ghosts of Tupelo Landing in this cozy ghost story about family, environmental activism, food, and friendship. Basil Theriot has spent her entire life in New Orleans—in her family’s famed Cajun restaurant in the French Quarter, really—but she’s never been out to the bayou where her grandfather grew up. She’s also never seen a ghost, even though dozens of ghost tours pass by the restaurant every day and her best friend Tommy is determined to be a ghost hunter. But then Grandpere’s ghost appears. And he has a mission for her. Basil wouldn’t mind being haunted if Grandpere could be helpful and share his secret recipe that might save the restaurant. But instead, he’s intent on connecting Basil with her Cajun heritage. He sends her out to the bayou to meet his friends: an airboat captain, a shrimper, and a scientist rebuilding Louisiana’s fast-disappearing coastline. For fans of Gracie Under the Waves and A Strange Thing Happened in Cherry Hall, Grandpere’s Ghost Swamp has a little bit of everything: a pinch of spookiness, a dash of environmental activism, and a heaping of family. “A lovely, cozy read that proves Rachel M. Marsh has ‘the gift.’”  - Marti Dumas, author of Secret Society of Rebel Girls “ Grandpere’s Ghost Swamp  is more than a book. It’s an experience. I could smell the fish market, taste the mirlitons, feel the bayou air, and hear the Zydeco music in the French Quarter.”  - M.R. Fournet, author of Brick Dust and Bones I was immediately pulled into the warm and bustling kitchen of the Theriot family’s New Orleans restaurant. Basil is a strong character who honors family traditions while carving out her own path, speaking up for the bayou and its inhabitants, and showing up for a friend when it matters most. A perfect recipe of humor, family connections, honoring the natural world, and a ghost with unfinished business. - Lynne Kelly, USA Today bestselling author of Song for a Whale. “In this slow-burn story . . . New Orleans and Louisiana’s Central Wetlands . . . shine as key characters. . . . A family story that highlights environmentalism and personal connection.” - Kirkus Reviews Through a blend of magical realism and regional detail, the novel offers a beautiful exploration of grief and familial expectation following a death. . . . This Cajun-soaked yarn about ghosts, family, and reconnecting with one’s roots will captivate readers; strongly recommended. - School Library Journal Rachel M.
